<span>Sr + O2--->2SrO</span><span>is the right answer</span>

<span>The correct answer would be the second option. It is the reaction Sr + O2 = 2SrO that is not balanced correctly. To be able to say that an equation is balanced, it should be that the number of each atom in the reactant and the product side is equal. As we can see, at the reactant side there is only one Sr while in the product there are 2 Sr atoms.

Below are the steps of the engineering process (not necessarily in order): 1) Know the background 2) Do the work 3) Make a plan
LuckyWell [14K]

Answer:

4 - 1 - 3 - 2 - 6 - 5

Explanation:

During an engineering process, first, we need to identify the problem, or the need because the process only will occur because of some need. Then, it's necessary to know as much as possible about the problem and the things that already exist or already were tested to solve it. Knowing the background will make the work easy.

After that, it's necessary to plan the things we'll do, knowing the costs, the time needed for activities, how many people will be necessary for each step, etc. It's really important to make a plan. Then, do the work, following the plan. Thus, the process must be tested. During the test of the results, some problems must be found, so it's time to evaluate and redesign the process, to solve these problems found.
